Welcome!

I am a PhD student from the Department of Sociology at the Chinese University of Hong Kong. I obtained my MPhil. Degree in Urban Governance and Design from the Hong Kong University of Science and Technology (Guangzhou) in March 2025. I was an exchange student at the Division of Social Science, the Hong Kong University of Science and Technology (Clear Water Bay), from January to August 2024. Before obtaining my master's degree, I worked as a research assistant at Peking University and Southern University of Science and Technology (SUSTech).

I am interested in social determinants of health across the life course, time-use research, and broader topics in quantitative social sciences (sociology and demography). My current research examines how information and communication technology (ICT) influences the mental health, social networks, and time-use behaviors of the elderly. Apart from my primary research agenda on health and digital inequalities, I am also interested in understanding the mechanisms by which social interventions can improve children's human capital in very low-income and less-developed areas. I primarily use firsthand local or secondhand national representative surveys (not limited to Chinese data), administrative data, population censuses, among other relevant structured or unstructured data in my current research. Methodologically, I adopt a multi-method approach, including design-based causal inferences (reduced-form estimation), social sequence analysis, computational methods (text-as-data and Large Language Models, LLM), and field/survey experiments.

I am open-minded and happy to collaborate with researchers from different disciplines (esp. STEM-related disciplines or economists). You can reach me via email: liuyongye16 [at] gmail [dot] com or through Departmental Homepage: https://www.soc.cuhk.edu.hk/profile/liu-yongye/
